vFURNACE FOR BURNING REFUSE.

SPECIFICATION forming part of Letters Patent No. 633,300, datedSeptember 19, 1899.

Application filed April 2 2 1 8 9 9.

*for heating the furnace.

The invention is drawings. y

Figure 1 is a longitudinal section through the middle of the furnace;Fig. 2, a transverse section on the line 2 2 of Fig. l, and Fig. 3 ahorizontal section on the line 3 8 of Fig. 2.

The furnace dis supplied through the opening do with coal-dust and airand through the hopper b with the refuse to be destroyed and is alsosupplied with air through the chamber bo, attached to the hopper. Bothsupplies of air for combustion are preferably previously heated by meansof the escaping gases from the furnace. The descent of the refuse to themiddle of the furnace is assisted by means of a mechanical stirringdevice consisting of bars c, provided with claws, which are worked toand fro by means of the shaft d, provided for this purpose witheccentrics. The furillustrated in the annexed nace-space d and the fluee for the escaping gases, which flue is preferably led to theheating-chamber of a steam-boiler, are connected by means of a passagee0, contracted so as to cause a portion of the gases to pass through theopening or slit f in the floor of the furnace, through which the moltenslag falls.

Serial No. 714,003. (No model.)

The gases thus passing through the opening f enter a central iiue g,which passes rear- -wardly beneath the sole of the furnace andcommunicates at its rear end with two lines h, one at each side of it,which conduct the gases beyond the contracted portion e0 also to theexit-flue. Beneath the opening f is placed the Water-trough z', upon thesloping bottom of which the bogies k move automatically from theentrance-point Z to the exitpoint rm. The middle part of the row of b0-gies is underneath the slag-outlet f. The spaces between the severalbogies are covered by' plates ko, which are fixed to the bogies, so thatthe whole of the slag discharged is passed into the bogies. The watercontained in the trough c' may be drawn off through the pipe n as soonas it becomes heated and may be used as feed-water for a boiler, whilethe inlet-pipe o is automatically opened and closed according torequirements by means of a ballcock 00.

The combination of a furnace, an exit-flue, and central and side fines,extending beneath the sole of the furnace, the exit-flue being providedwith a contracted portion next to the furnace and the ioor of thefurnace be-
